Pointless?
My problem with the assumption that most will need to link to access (work) documents across multiple devices is not what I see. Where I work, we are issued a laptop which allows us to work either in the office or remotely via a VPN. Very few of the staff are issued a company phone or tablet in addition to the laptop (I personally do not know of anyone who has a phone or tablet). So, the only approved way for most of us to access company documents is through the company laptop. With my personal stuff, when I am traveling I typically am not keeping up with email or typically actively working on a project. If I plan to, it is just as easy to put the documents on a thumb drive and use that for syncing. Also, when actively working on a document, etc. a laptop is the minimum device that works reasonably well.
